Optec - NextGEN WideField 0.5X Telecompressor Kit.

Details

The Optec NGW (Next Generation WideField) telecompressor increases the effective speed of the Meade and Celestron Schmidt-Cassegrain telescopes from f/10 to f/5. This 1/2 times reduction in focal length allows for 4 times greater field area and 1/4 reduction in exposure time for extended surface objects such as bright nebulae. The system is optimized specifically for f/10 Schmidt-Cassegrain telescopes to allow for correction of the field curvature and spherical-chromatism that afflicts these types of instruments. At f/5, the maximum corrected field has a diameter of 17.5 mm at the image plane which makes the optic suitable for CCD cameras with imaging chips of the same diagonal dimension or smaller.
